CenturyLink vs Xfinity: Which Is Better in 2026?

Based on plans tracked in the Konecteaze database, Xfinity has the lower entry price at $40/mo, compared with $50/mo for CenturyLink. Promotional pricing, fees, and regional offers can change the real monthly total, so confirm at checkout.

On the fastest plans we track, CenturyLink reaches 8 Gbps download versus 2 Gbps for Xfinity. These are advertised plan speeds — real-world performance varies by address, wiring, and network load.

Sometimes — provider footprints overlap in many markets but coverage is decided block by block, and our plan records are provider-level, not an address-level serviceability check. Enter your ZIP code on Konecteaze or run each provider's address checker to confirm which one (or both) actually serves your home.

Order the new service first and confirm an installation date before cancelling the old one, so you are never offline. On installation day, verify speeds, then cancel the old plan, return any rented equipment to avoid fees, and check your final bill for proration. If you are under contract, ask about early-termination charges before scheduling.

Plan names, prices, and speed fields come from the Konecteaze provider database — the same records behind our provider pages and comparison tool. We currently track 4 CenturyLink plans and 4 Xfinity plans. Fields we cannot verify are omitted rather than estimated, and affiliate relationships never change the data shown.

Xfinity rates higher in our database at 3.4/5, compared with 3.3/5 for CenturyLink. Ratings reflect reviews collected on Konecteaze and are one signal among the plan facts above.

CenturyLink's network is a mix — some addresses still run on its older DSL (copper) lines, while a growing share get its Quantum Fiber build-out, which delivers symmetrical speeds. Xfinity is a cable network nationwide, sharing bandwidth on the line and typically delivering much faster downloads than uploads. Which CenturyLink technology you're actually offered depends entirely on your address, so confirm that before comparing it to Xfinity's cable line.

Both have generally moved toward no-annual-contract, month-to-month pricing in most markets, though promotional rates on either can step up after an introductory period and terms vary by address. Confirm the current contract length and how long your quoted price is locked in before signing up with either.

If CenturyLink's fiber (Quantum Fiber) reaches your address, its symmetrical speeds are usually the stronger pick for uploading, video calls, and remote work. If only CenturyLink's older DSL service is available at your address, Xfinity's cable network will generally outperform it on speed. Check which CenturyLink technology actually serves your address before assuming either provider is faster.

The only reliable way is to check serviceability directly, since fiber and DSL availability are decided block by block and CenturyLink's fiber build-out is still expanding market by market. Don't assume based on a neighboring address; confirm the specific technology quoted for your address before comparing plans against Xfinity.
